My invention relates to improvements in steam cleaners, and the objectof the invention is to devise a simple means for removing particles offoreign matter from the 5 steam so that such steam will be freetherefrom as it passes to the engine preventing the detrimental effectthereof in the steam cylinders and other parts of the engine, and itconsists essentially of the arrangement anc 1o construction of parte ashereinafter more particularly explained.

Fig. 1 is a sectional view through my steam cleaner.

Fig. 2 is a plan sectionalview on line 22 15 Fig.

n the drawings like characters of reference indicate corresponding partsin each figure.

1 indicates a cylindrical casing provided I with upper and lower heads 2and 3. 4 is a clean out orifice in the lower end of the cylinder casing1.

-5 is a ciylin rical member which de ends centrally rom the head 2 andis provi ed at 35 its lower end with an out turned annularinclined'tlange 6 forming a constricted annular opening 7 between t elower edge of the flange and the internal periphery of the casing 1. 8is a feed inle steam pipe leading tan entially into the casing 1 at itsupper en'. The steam is fed under pressure through the pi e 8 into thecasing and travels around suc casin between the internal eripherythereof an the exterior of the cyindrical member the flange 6 tending toresist the Adownward passage of the steam so that a whirling action isprovided forcing the steam outward against the interior periphery of thecasing, the steam passing slowly down through the mouth7.

By this action the foreign particles in the 'steam which are the heavierparticles are carried outward by centrifugal action against the internalsurface ofthe casing and fall downward by gravity, the main body of thesteam passing through the mouth is carried through the open end andperforated top of the vertical steam outlet pi e 9 which is secured inan orifice 10 terme in the lower 1 pacers 13 are provided to in theconical member 11.

head 3 of the casing in order to further resist the downward passage ofthe steam.

A hollow conical member 11 is carried by the outlet pipe 9 intermediatelofthe height thereof and of the 1eight o the casing 1 so as to form avery small opening or passage between the periphery o such member andthe internal peripher. of the casing. old the member in proper relationto the casing l. 14 are perforations formed in the u per portion of theconical member 11, an l5 is an annular baie flange carried the pipewithpasses downward through the passa Pe 12.9.1161 which serves also tocarry the partie es downward when it has passed through such mouthpasses u ward into the conical member 11 as t the aille plate 15 andvthrough the orifice 4 into the main llow of steam passing outward intothe upper end ot the pipe 9.

The baiile plate 16 insures t iat no articles of foreign matter passupward wit this out flowing steam. The particles of foreign matterpassing downward'by gravity past the conical member 11 collect in thebottom of the casinghl and are cleaned out periodically throng the cleanout orifice 4c.

lFrom this description it will be seen that I have devised a very simpledevice whereby all particles of foreign matter may be removed lrom livesteam so as to render it more suitable 'for consumption.

What I claim as my invention is 1 A steam cleaner comprisin acylindrical casing havin upper and ower ends, esteem. inlet pipe lea ingtangentiallv into the upper end of the casing, a cylindrical memberdeending centrally, from the upper casing cad to form an annularinterspace between.

itself and the wall of the casing and having an out turned lower edgeportion forming a constricted annular steam outlet Within the casing, asteam dischar e outlet leadin through the lower end o the easing, anmeans for bailling that ortion 0l.' the steam with the descending paricles of foreign mat ter to prevent the upward passage of such matter tothe steam Outlet.

2. A steam cleaner, comprising a cylinlill e steam which drical casinghaving upper and lower heads,

a steam inlet lpipe leading tangentially into the upper end of thecasing, a cylindrical y member supported centrally by the upper casinghead to form an' annular interspace between itself and the wall of thecasing and having an out turned lower edge portion forming a constrictedannular steam outletwithin the casing, a steam discharge tube arrangedaxially within the casing and passing through the lower head thereof,and means carried by the tube for forming a constricted annular mouthbetween itself and the internal periphery of the casing and means forre- 4 turning the steam passing outward through such restricted mouthwith the foreign particles of matter back into the main flow of steampassing through the upper end of the discharge outlet.

3. A steam cleaner comprising a cylindrical casing having upper andlower heads, means for feeding the steam tangentially into the upper endof the casing to'permit the foreign particles of matter contained in thesteam to be carried out by centrifugal action against the innerperiphery of the casing to pass downward and a steam discharge pipeextending centrally and longitudinally of the casing through the lowerend thereof, a conical member carried by the steam discharge pipeintermediate of the height of the casing and forming an.annularconstricted outlet between itself and the wall of the casing throughwhich the particles of foreign matter are adapted to fall, and means forreturning the steam passing downward with such particles of foreignmatter into the main steam iow to pass outward through the discharge.' 1
